WhiteRock Lithium has intersected spodumene-bearing pegmatite in all 10 newly reported drill holes at its Spodumene Mountain prospect in Québec. The visual results strengthen the geological case for continuity, but assays and true widths are still pending.
- Spodumene-bearing pegmatite intersected in all 10 new holes
- Six holes recorded individual pegmatite intervals exceeding 50 metres downhole
- BL26-044 returned three intervals with 25-35% visually estimated spodumene
- Four drill rigs are now active at Spodumene Mountain
- Assays expected within three to six weeks
Ten-for-ten drilling result extends the geological picture
WhiteRock Lithium Corp. (ASX:WLC) has reported spodumene-bearing pegmatite in all 10 new diamond drill holes at Spodumene Mountain, adding another layer of geological continuity to the Banana Lithium Project in Québec. The holes, BL26-037 through BL26-046, were drilled across southwest, northeast and central parts of the prospect as the company shifts from testing the system’s lateral extent toward defining its geometry and continuity.
The latest campaign has also produced substantial downhole intersections. Six holes returned individual pegmatite intervals longer than 50 metres, including 84.0 metres in BL26-041 from 8.0 metres and 78.1 metres in BL26-046 from 28.8 metres. The company says several holes intersected multiple stacked pegmatites, suggesting a system made up of more than one mineralised body rather than a single continuous sheet.
Central drilling delivers the strongest visual observations
The most notable visual results came from the centre of Spodumene Mountain. Hole BL26-044 intersected three intervals longer than 10 metres with visually estimated spodumene abundances of 25% to 35%: 51.0 metres from 52.5 metres, 29.9 metres from 162.9 metres, and 14.5 metres from 197.3 metres downhole. BL26-041 recorded an 84.0-metre pegmatite interval with a visual spodumene estimate of 15% to 25%.
Those numbers are attention-grabbing, but they remain geological observations rather than grade results. WhiteRock has not yet established true widths, and the visual estimates cannot substitute for laboratory analysis of lithium concentration, mineralogy or potentially relevant impurities. The company says spodumene is predominantly coarse-grained, with crystals ranging from centimetres to decimetres in scale.
Four rigs target depth and resource definition
Seventeen holes in the 2026 drilling campaign have now been completed, logged and sampled for a total of 4,435 metres, with 2,532 metres represented in this release. A fourth diamond drill rig was mobilised in September, and the program is scheduled to continue through October as drilling tests the down-dip continuation of the pegmatites along the known strike.
WhiteRock says the Spodumene Mountain system remains open along strike and down dip. Its stated objective is to use the ongoing drilling and assay program to support a maiden Mineral Resource Estimate in the first half of 2027, although that timetable remains conditional on the results of the work still underway. Laboratory assays for this batch are expected in roughly three to six weeks, creating the next meaningful test of whether the visually consistent pegmatite translates into commercially relevant lithium grades.
Bottom Line?
The drilling is building a more coherent geological model, but the investment case still turns on assays, true widths and whether continuity holds at depth.
Questions in the middle?
- Will the pending assays confirm the strong visual spodumene observations with consistent lithium grades?
- How closely will true widths match the reported downhole intersections once the geological model is refined?
- Can the expanded drilling campaign deliver enough confidence for a maiden Mineral Resource Estimate in the first half of 2027?
